identical twins cannot be different genders. they are split from the same egg meaning their DNA is identical at the point of conception including their chromesones.
fratenal twins are basically two babies that share the womb. two seperate eggs and sperm.

20 is right identical twins have to be the same gender so there DNA is the same: males have X and Y chromosomes and females only have Y. So in order for twins to be identical they need to be the same sex. :)

20 are you sure it's different eggs as well? I thought it was just different sperm same egg, then again I never looked into it. If what I said is true, then they share all of their mother's genes, which means more similarities than normal siblings.

having researched a wee bit yoy can have very rare cases of identical twins where one is male and one is female. it is caused by a mutation in one male twin. identical refers to the zygote meaning they have ti be from the same zygote.

Actually identical twins are always the same gender. Contrary to common misconception, boy girl twins can not be identical. Also, fraternal twins are two different eggs and sperm. However, it is possible for fraternal twins to look similar and for identical twins to look slightly different.

My parents call me by my brothers' names all the time, don't feel that bad. I have even accidentally called my dog by one of my brother's names, and they look nothing alike.

Today, I was following my dad while texting, not really watching where we're going. Suddenly, he ran ahead and I looked up to see what he was doing. We were in the men's bathroom. There were 3 guys at the urinals. I'm a 15 year old girl. FML
